In a large bowl, mix flour, salt, yeast and water until combined. Cover with plastic wrap and let it rise for 6-12 hours at room temperature.
Transfer the dough onto a floured work surface and dust the top of the dough with flour. The dough will be very sticky, gently shape the dough into a ball using a spatula or your hands. It doesn't need to be perfect!
Place dough in a bowl lined with parchment paper. While the dough is resting, preheat the oven to 450°F with the Dutch oven. Once at 450°F, let the Dutch oven preheat for 15 more minutes.
Remove the Dutch oven, lift the dough with parchment paper into the pot. Cover and bake for 30 minutes. Remove the lid and bake for 10-15 minutes.
Transfer the bread onto a cooling rack for 20-30 minutes before slicing.
Notes
Fresh bread lasts about 2-3 days. Freeze a whole loaf or slices of bread for up to three months in a freezer bag.
